`:POCKET OR DESK IMPLEMENT.

Specioation of Letters Patent.

Patented Aug'. 6, 1907.

Application led September 29, 1906. Serial No. 336.736.

To all 'whom 'it mayvconcern: v

Be it known that I, OSCAR M'UssrNAx, a citi/,en of the United States, residing at Arverne. borough of Queens, New York city, Stateof New York, have invented an'lmprovement in'Pocket or Desk Irnplements, of which the following is a speciiication.

My invention relates broadly to a telescoping structure, the parts of which as is thereby implied-are longitudinally movable and adjustable one within another and the construction of the same is such that the parts are adapted to be gripped or bound together in any longitudinal position by a slight revoluble movement and While my pr'esent invention is capable otv numerous applications, l prefer to show and describe the same as embodied in a pencil, penholder. or other pocket or desk implement.

Heretoiore pocket or desk implements, such for instance as pencils, penholdors, erasers or other similar utensils, have been made and provided with devices ior'protecting the actual wor'king parts when not in use; for example, pencils have been made with a sheath or body portion adapted to receive lead or Working parts, the body portion being closed at one end and provided at the other end with a screw clamp or other head, in and by which the lead may be adjusted to the desired position and gripped. Pencils have also been made with a sheath or casing lifted with telescoping pull and push members for advancing a lead holding member to its working position and' retraeting the same to a position in which the lead is protected Within the sheath. Penholders too have been provided with caps or covers adapted to protect the pen and particularly the nibs thereof when not in use, and erasers, paper' cutters and various other pocket or desk implements have been similarly provided with means for protecting the working parts thereof.

M y present invention as embodied in a. pocket 0r desk implement, results in a simply Constructed pen: cil, penholder' or other similar utensil, in which the working part or' member may be easily adjusted to and secured in its Working position and as readily adjusted to and secured in its non-working or protected position within a suitable sheath or (rising, and in carrying out my invention, l employ a sheath or casing as the member adapted to be gripped by the hand in the use of the implement, a telescoping member movable longitudinally and revolubly within the said casing and adapted in one revoluble position to be adjustable to any longitudinal position within the said. easing and said casing to secure these parts together, a working member' and means i'or connecting the working member with the said slidable telescoping member as will liereinater be more particularly described.

in the drawing, Figure l is a central longitudinal section and partial elevation oi a lead pencil embody-` ing my present invention. Fig. 2 is a cross section on line x, fr, Fig. l. Fig. 3 is a cross section showing the inner or' telescoping member turned to engage a por' tion of the casing to bind the members together'. Figs. 4 and 5 are central longitudinal sections illustrating modifications of my invention and Fig. 6 is a cross sec tion on either line y, y, Fig. 4, or line z, z, Fig. 5. Figs. 2, 3 and 6 are made on an enlarged scale.

Referring to the drawing and particularly to Figs. l, 2 and 3, a designates a sheath or casing which may be made ol any suitable material and which for the greater part of its length is cylindrical in cross section. One end b ot' the casing a is of reduced cross section and moreover' is made elliptical in outline. Secured to or' integral with the opposite end of the casing a is a head or tip c. d designates a telescoping member' which may also be made of any suitable material and whose ends are both circular incross section and in one of which a knurled thumb piece 2 is secured and in tho other is a plug 3 or other' means adapted to receive and securely hold in position a gripping member 5 by which a leadf is held. This teleseoping member' d is provided longitudinally with a flattened portion indicated at e preferably extending from a point adjacent to one end thereof to a point similarly adjacent to the other end thereof. Now the relation of the hereinbei'ore described parts is such that the minor inside diameter of the elliptical end b of the casing a is less than the major diameter of the telescoping member' d, so that in one position,-that is to say,-wl1en the line through the center ot the telescoping member' passing centrally through the flattened portion thereoi' is in line with the inner minor diameter of the elliptical end4 b, the telescoping member' d is readily movable within the casing a and inasmuch as the lead f is adapted to pass through the tip c7 it will be apparent that the same by moving tho telescoping member rl may be adjusted to any position with its end or pointl oulsideol' the tip c to the working position or within the tip c on the casing a to the non-working or pro tecled position. It will further be manifest that in any longitudinal position7 the casing a and the telescoping member d may be secured together by imparting a slight rotation Lo iheparts in either one direction or the other, in doing which the flattened portion oi' the telescoping member' will be turned from the position shown in Fig. 2 lo thatshou'n in Fig. 3, thereby causing a portion oi the surl'ace or the telescoping member j rl to engage the inner' surface of the elliptical end b oi in other revoluble positions to bind a portion o1' :he

the casing u, tending to force the same from its elliptical lo a circular position, whereby the said parts are boundY together by a l'riclional grip. Moreover as the exterior major diameter' or' the telescoping member d is slightly greater than the minor inner' diameter of the elliptical end Il, it will bc apparent that the telescoping member may be entirely withdrawn from the casing a by forcing the end 4 of .-.he telescoping member through the elliptical end b, but that in View of this relationship, the parts Will not normally become separated.

Referring to Figs. 4 and 5, wherein I have illustrated my inventionias en'ibodied in a penholder and eraser, a is a sheath or casing and b its reduced end of elliptical outline.

lnfiFig. 4, h designates the shank ofv the penliolder Whose end as is customary, is provided with a socket comprising a sleeve 6 and an internal split member 7, between which the shank of a pen 8 is adapted to be received and secured in position. A portion of the penholder shank h is provided with a liattened portion h and the relationship of these parts to the casing aand its reduced elliptical end is similar to that hereinbeiore described in connection withl the pencil, making the same beth longitudinally movable and adjustable in such positions, that the pen may be adjusted to `a Working position Without the Casing and secured in position or retracted to its protected position within the casing a and there secured.

Referring particularly to F ig. 5, i designates a shank7 one end of which is provided with a sleeve 9 adapted to receive an eraser l0, which may be secured Within the casing a or moved therefrom to a Working position by meansot the adjustment of the shank i which is provided with a flattened portion 1;/ similar to that provided in the like members hereinbeore described.

While I have shown and described my present invention as applied to a pencil or other pocket or desk implement, I do not Wish to be understood as limiting myself to any such application as the same is capable ol other applications Without departing irom the nature and spirit of my invention.

I claim as my invention:

sea,

within 'the other and adapted i; one revoluble position to be moved longitudinally and freely the one within the other and in the other revoluble positions to be frictionally held together.

3. A pocket implement comprising an exterior member and an interior member revolubly and longitudinally moyable and adjustable in said exterior member and adapted n in one revoluble position te be freely moved longitudinally within the exterior member and in other revoluble posi- .tions to bind a portion of the saidexterior member to secure the parts together.
